The Wago 793-5501 terminal block accessory featuring a WMB marker card is designed specifically for terminal widths ranging from 5 to 17.5 mm. Supplied in a clean white color, this component plays an essential role in clear and organized circuit identification during electrical installations. It supports efficient wire management and long-term maintenance by ensuring every connection is properly labeled and easily identifiable within complex control panels or junction boxes.

Advantages

This marker card utilizes the reliable WMB Multi marking system to deliver consistent and legible labeling for industrial and commercial electrical setups. The cards are stretchable from 5 to 5.2 mm, offering flexibility to fit terminal blocks securely and snugly. Each card includes multiple strips with individual markers, allowing technicians to label large numbers of terminals quickly and uniformly without requiring custom printed labels for every single connection.

Suitable for

• Electrical control panel assembly and wiring
• Industrial automation and machinery maintenance
• Terminal block organization for widths between 5 and 17.5 mm
• Commercial building electrical installations

When it may not be suitable

This product is not appropriate for terminal blocks with widths outside the 5 to 17.5 mm range, as the markers will not fit correctly. It is also not suitable for outdoor environments where continuous exposure to extreme weather or direct moisture could degrade standard paper or plastic marker materials without additional protective enclosures.

How to use

To apply the markers, gently detach the required number of individual markers or strips from the WMB marker card.

What to consider before purchase

• Verify the exact width of your terminal blocks to ensure they fall within the 5 to 17.5 mm range
• Check whether your setup requires plain markers or pre-printed custom numbering
• Ensure compatibility with the WMB Multi marking system used in your installation

Usage recommendations: Store the marker cards in a dry, dust-free environment prior to application to maintain optimal adhesive and material integrity. Apply markers at room temperature for the most secure fit onto the terminal blocks.
